im back again everyone, i plan on using a sterlite tub for my ball. i know i need a thermostat to regulate the UTH and thermometers with a probe, but im concerned with the cool side. the temps in my room stay between 72 and 75 but if i were to use a light would it melt the plastic ? im not to worried about humidity because i live in my basement and its generally humid down here. again my main concern is the light and plastic melting. any advice would help, thank you.
